To all :whom it may concern:

Be 1t known that we, Gunmmuo Corrmr and Gmonano Comm, both'citizens or the United States of America, and residents of like to make it ready to be cut and formed into bundles or packages, and consists essentially of certain peculiar mechanism for folding lengthwise a strip of 'paper, apply.-

ing small particles or drops of adheswe'material to such paper after being folded, and

winding the paper thus layeron a reel or drum, all as hereinafter. set, i

prepared layer upon forth.

The primary object or our invention is to A vide a machine wherewith maybe economically and expeditiously produced toilet paper, folded and treated with an adhesive, in readiness to be cut into the proper widths for packages, which packages shall consist of folded sheets, with contiguous folds or laps of adjacent sheets attached-by means of such adhesive, such a package, for example, as that which forms the subject matter of our application for United States Letters Patent filed on even date herewith and serially numbered 813,697.

we will proceed to A further object is to pro zide such a machine which is simple in construction and operation, comparatively inexpensive, and withal highly practicable and efficient.

Other objects and advantages will appear in the course of the following description.

A preferred form of embodiment of the invention, whereby we attain the objects and secure the advantages of the same, is illustrated in the accompanying drawings, and describe the invention with reference to said drawings, although it is tobe understood that the form, construction, arrangement, etc, of the parts 1n various aspects. are not material and may be modified without departure from the spirit of the invention. s

g The main frame of the machine consists of a pair of side beams1 ,a cross-piece 2 conv lneeting the right-hand orfront ends ofsaid ;-may be termed the'front side of the machine or the side next to the beholder ,3 on such side, with the exception offthe bot- ;tom part or" the right-hand one.

to the front end of the aforesaid frame, at the top, is a cross-pieced. is inserted between the frontlegs 3, and a vertical bearing support 6 rises from the floor oustide or to the right of the frame and adjacent tosaid legs. This support is omitted from Fig. 5. In advance of the vertical plane of the front side of the .frame is a support 7 having a pair of vertical bearing arms 8.- The support 7 rests on the door and is clearly shown in Figs. 3 and 5.

A shaft 9, for a supply roll 10 is journaled in the arms 8.

Attached I The supply roll 10 consists 1 being omitted V pair of bearing blocks A of a long strip of toilet paper wound into;

roll formation on the shaft 9.

Mounted on a shaft 11', which is-journaled in the front leg 3, that is adjacent to the support 7, and in the support 6, is a guide roll 12. The shaft 11 is parallel with the shaft 9, but below the said shaft 9.

Mounted on a shaft 13, which is journaled in the cross-piece 5 and the support 6, is a horizontal plane of orizontal plane folding roll 14. The roll 14 is in the form of a double cone having a common central base. Cooperating with or assistin the roll 14 in the folding operation is a older plate 15. The plate 15 1s hinged at 16 to a stationary plate 17 mounted on a bar 18 that extends tween the cross-piece 5 and the upright 6. In the front or free end of the plate 15 is a V-shaped notch 19 through which the roll 14 revolves. The plate'15, when in operative osition, is approximately in line with the ii of the axis of the roll 14. The hinges 16 afford means for turning the plate 15 upward and away from the roll 14, into the position shown by broken lines in Fig. 5, and for returning said plate to operative position relative to said roll. As will presently be more fully explained, the strip of paper from the roll 10, which strip is represented at 20, passes upward through the notch 19 in the plate 15, between the roll 14 and said plate, and in order that this action may occur without said plate being raised by the drag of said strip thereon, or, in other words, by the frictional contact of the paper with the edges of the notch 19, said hinges should have tight joints in the absence of special locking means. The weight of the plate 15 is also a factor in re taining it in operative position and resisting the upward tendency that the strip 20 would otherwise naturally impart to it. The shaft 13 is parallel with the shafts 11 and 9, but above the horizontal plane of the axis of either of the two latter.

A pair of contiguous creasing rollers 21 is mounted on a pair of shafts 22, which shafts are journaled in the bearing blocks 4, such rollers being above the folding roll 14 and arranged at right-angles to the herebeforementioned rotary members, including said roll. A guide roll 23 is mounted above the inner roller 21- on a shaft 24, which shaft 24 is journaled in bearings 2525 secured to the upper contiguous edges of the blocks 4 and beams 1. The roller 23 is parallel with the rollers 21, as are all of the other rotary members yet to be described.

A guide roller 26 is mounted on a shaft 27 which is journaled in bearings 2828 provided for said shaft on the beams 1. The axes of the rollers 23 and 26 are in the same horizontal plane, and said rollers are alike in diameter. Next in order from the front end of the machine is a guide roller 29 mounted on a shaft 30 which is journaled in bearings 31-31 on the beams 1. Theroller 29 is situated below the horizontal plane of the rollers 23 and 26.

A shaft 32 is journaled in bearings 33 which are provided therefor on the beams 1 adjacent to their left-hand or front ends,

and a winding drum 34 is mounted on said shaft.

Midway between the bearings 25 and 28 on each side of the frame is a bearing 35 on each beam 1, and journaled in the two bearings 35 is a shaft 36 having mounted thereon a pin-wheel 37. The wheel 3'7 is provided with a series of radial pins 38 that project from the periphery of said wheel and have a common vertical plane which is at rightangles to "the wheel axis. The dimensions of the parts are such that the outer ends of the pins 38, as the wheel 37 revolves, pass slightly above, at the highest point of their revolution, the horizontal plane of the tops of the rollers 23 and 26, so that said pins in turn or one after another contact positively with the paper on'the underside as it passes from said roller 23 to'said roller 26.

J ournaled directly below arings on the undersides of the beams 1 and similar to the bearings 35, is a shaft 39. Abracket or hanger 40, which is attached at its ends to the inside faces of the beams 1, carries a box 41 which is designed to contain paste, gum, or other suitable adhesive material in liquid or semi-liquid form. The shaft 39 passes through the sides of the gum box 41, and a furnisher roll or gum roll 42 is mounted on said shaft in said box. The diameter of the roll 42 is such that the outer ends or heads of the pins 38 contact with said roll, as the wheel 37, revolves, and so receive. thereon particles or drops of the gum or adhesive material, which particles or drops are transferred to the paper by said pins.

Power from any suitable source is transmitted to the gum-roll shaft 39 through the medium of a belt 43 and a pulley 44 on said shaft. Likewise power is transmitted to the drum shaft 32 through the medium of a belt 45 and a pulley 46 on said shaft, and to the pin-wheel shaft 36 by means of a pulley--47 on said last-mentioned shaft and a belt 48 which connects said last-mentioned pulley with the drum 34.

There is a groove 49 in the guide roller 26, in line with the pins 38, through which the drops of gum deposited on the paper by said pins pass. This provision prevents the gum on the paper from coming into contact with the roller 26 and so interfering with the successful operation of the machine.

In practice, the supply roll 10 is mounted on the shaft 9, and the strip 20 therefrom is led from the top of said roll beneath the guide roller 12, and thence upwardly behind the folding roll 14 and between said roll and the folder plate 15. The plate 15 is raised while the strip 20 is being first led up behind the roll 14, and then said plate is turned down again. In passing through the folder the strip 20 is folded lengthwise with a wide lap 50 and a narrow lap 51, as shown in Figs. 1, 2 and 5. The paper is creased at 52, Figs. 1, 2 and 5, by the rollers 22 to make the laps permanent. The folded strip is designated by the shaft 36, in

said plate being radial to the axis of said ported, and means to supply an adhesive to roll, creasing rollers for such folded strip, the pins carried by such wheel.

such rollers being approximately atright-an- GULIELMO COTTINI.
